Description:Elvis, a five-metre half-tonne croc, grabs a lawnmower and drags it into his pool to "kill" it. His attack was so vicious two of his teeth were left lodged in its blades. The monster, who has lived at Sydney's Australia Reptile Park for three years, has been called Australia's meanest croc following the "attack". Elvis charged at the two workers when they entered his enclosure with the lawnmower to give the grass a trim.(0:16)
